Annex N
(normative)
Description of the reference machine [Type 2]

NOTE The old reference machine [Type 1] with similar performance values is described in Annex E.
N.1 Specification of the reference machine
NOTE 1 A suitable reference machine that complies with the requirements of Clause N.1 is the Miele G 1222 SC
Reference (Writing on faceplate: Miele G Reference) that has been specially prepared for use as a reference
machine by Miele. A complying reference machine can be obtained from the supplier as specified in Clause F.16.
“Miele” is a trademark. This information is provided for the convenience of users of this international standard and
does not constitute an endorsement by the IEC of this trademark. Items of the similar specification may be used if
they can be shown to lead to equivalent results.
General specifications and performance requirements:
– rated voltage 230 V a.c., rated frequency 50 Hz (refer to N.2);
– rinse aid dosage: setting 3.
Specifications of the reference programme (name of the programme on the faceplate of the
reference machine “Reference EN/IEC“) using a clean load with no detergent:
– spray arm rotations per min: top: 41 ± 9 (refer to N.3.2)
middle: 24 ± 4
bottom: 35 ± 5
– water hardness of sump water in the 2 heated rinses [mmol/l]: ≤ 0,5 (refer to N.3.3)
– water consumption [litres]: 14,4 ± 0,4 (refer to N.3.4)
(with regeneration of the softener) [litres]: 16,9 ± 0,5
– energy consumption [kWh]: 1,33 ± 0,08 (refer to N.3.4)
– water level measured in the sump at the end of the programme (refer to N.3.5)
– maximum water temperatures measured in the sump [°C]:
• cleaning operation: 50 ± 2 (refer to N.3.6)
• heated rinse operations: 67 ± 2 (refer to N.3.7)
– programme time [min]: 99 ± 4 (refer to N.3.8)
NOTE 2 As the new reference machine has no fan action after the end of the programme (as the old one), here
programme time and cycle time are identical.
Specifications of the reference programme (name of the programme on the faceplate of the
reference machine “Reference EN/IEC“) when tested in accordance with Clause 6 (soiled load)
using 5 g + 20 g (pre-wash + main wash) detergent B:
– cleaning performance – oven drying method (refer to 6.5.1):
average values 3,55 ± 0,20 (refer to N.3.8)
NOTE 3 Single values may scatter by ±0,15 around average values.

60436 Amend. 1  IEC:2009 – 5 –
– cleaning performance – air drying method (refer to 6.5.2):
4,02 ± 0,20 (refer to N.3.8)
NOTE 4 Range for cleaning index for the reference machine using detergent C is under consideration. Further
information may be available from the supplier of the reference detergent – see Annex F.
Specifications of the reference programme (name of the programme on the faceplate of the
reference machine “Reference EN/IEC“) when tested in accordance with Clause 7 (clean load)
using 5 g + 20 g (pre-wash + main wash) detergent B:
– drying efficiency: 0,81 ± 0,09 (refer to N.3.9).
Details on verifying the performance of the reference machine are set out in Clause N.3.
N.2 Installation and use of the reference machine
The manufacturer of the reference machine shall specially measure and check each individual
reference machine prior to supplying it.
For installation of the reference machine:
• check that the hoses are not bent. The height of the drain hose (measured from the
bottom of the machine to the highest point of the hose) shall be: 60 cm ± 10 cm;
• the reference machine is always installed as a free standing type, irrespective of the type
of test machine(s);
• the supply voltage and frequency of the reference machine shall be 230 V ± 1 % and 50
Hz ± 1 %, irrespective of the voltage and frequency of the test machine(s);
• the reference machine always uses a load style from Annex A, irrespective of the load
style used on the test machine(s).
N.3 Calibration of the reference machine
N.3.1 General
Before starting a series of tests, a calibration check of the reference machine shall be
undertaken. To perform a calibration check on the reference dishwasher, the following
measurements or observations shall be made and compared with the specifications and
requirements given in Clause N.1. If the machine does not comply with the specified
requirements, the test conditions, equipment and procedure shall be checked and the
measurements repeated as appropriate. If there are no apparent faults but the reference
machine still does not meet the specifications, contact the manufacturer to get this rectified.
Prior to performing calibration checks, ensure that all filters have been cleaned and that spray
arm jets are free from any blockages. It is recommended that calibration checks be
undertaken in the following order.
NOTE The checks on the reference machine specified in Clause N.3.2 to Clause N.3.7 can be verified with a
single cycle with a clean load and without detergent. Tasks specified in Clauses N.3.8 and N.3.9 are verified over 5
cycles.
N.3.2 Checking spray arm rotations
A service viewing window and associated key shall be used with the reference machine to
facilitate the performance of calibration checks of spray arm rotations. Spray arm rotations
may be determined on any programme on the reference machine with a clean load installed
and no detergent. If the spray arm requirements specified in Clause N.1 are not met, remedial
action shall be taken, e.g. contact manufacturer.

– 6 – 60436 Amend. 1  IEC:2009
N.3.3 Checking the water hardness
When the reference machine is run on reference programme (name of the programme on the
faceplate of the reference machine “Reference EN/IEC”) with a clean load installed and no
detergent, the values specified in Clause N.1 shall be achieved. The hardness is to be within
the prescribed range.
N.3.4 Checking the energy and water consumption
When the reference machine is run on reference programme (name of the programme on the
faceplate of the reference machine “Reference EN/IEC“) and in accordance with Clause 6,
except with a clean load at room temperature and no detergent, the total energy consumption
and water consumption values specified in Clause N.1 shall be achieved.
In each 5th cycle a regeneration operation occurs, respectively the water softener is rinsed
out.
N.3.5 Checking the water level in the sump
The water level left in the sump is used as an indicator of the drain pump performance. The
water level shall be measured at the completion of a cycle by removing the sieve. There is no
adjustment for this parameter—a machine that operates outside the specified range will
require servicing.

the end of programme
IEC  1818/09
N.3.6 Checking the water temperature in the sump
The water temperature in the sump is used as an indicator of temperature control
performance of the heating system in the reference machine. The water temperature shall be
measured on the reference programme during the h
